Abstract
An apparatus for controlling an automatic transmission of an automotive vehicle, which is shifted to a selected one of operating positions by an engaging action of a frictional coupling device, wherein an overshoot engagement control device is provided to shift the automatic transmission to the selected one operating position such that a shifting action of the automatic transmission is initiated while an input speed of the automatic transmission is lower than a synchronizing speed of the selected operating position. The overshoot engagement control device is arranged to control an engaging force of the frictional coupling device such that the input speed is first raised above the synchronizing speed and is then lowered down toward the synchronizing speed.
